>>713049695 (OP)Making the main villains correspond to the seven deadly sins is a neat concept, but it doesn't really work. Kanashiro fits greed more than gluttony, but they couldn't give greed to him because that was already Okumura's sin. No one has sloth, even though that could have been Madarame's sin. Instead, he's given "vanity" which is not only not one of the seven deadly sins, but is essentially the same thing as pride.
Royal makes this even worse because Maruki isn't given a sin; his trait is "sorrow". Wtf? The seven deadly sins and all the other villains were characterized by their desires. But sorrow has nothing to do with Maruki's desires except in a tangential sense.
